Abstract

Una struttura radiografica comprendente: un elemento radiografico che comprende un supporto e strati anteriore e posteriore di emulsione agli alogenuri di argento stesi sulle facce opposte del supporto, e una coppia anteriore e posteriore di schermi di rinforzo rispettivamente adiacenti a detti strati anteriore e posteriore di emulsione, in cui almeno uno di detti strati di emulsione agli alogenuri di argento mostra un indice di rigonfiamento inferiore al 140% e un tempo di scioglimento tra 45 e 120 minuti, e la differenza di contrasto tra della coppia di strati di emulsione agli alogenuri di argento è almeno 0,5, in cui la differenza di emissione di luce, stimolata dal raggi X tra detta coppia di schermi di rinforzo è almeno 0,6, e in cui il cross-over medio a guisa di immagine di detto elemento radiografico è inferiore al 5% a densità ottiche tra 0,5 e 1,75 e nell'intervallo tra il 5% e il 15% a densità ottiche tra 1,75 e 3,25, detto cross-over a guisa di immagine essendo misurato secondo la formula descritta nella descrizione.A radiographic structure comprising: a radiographic element comprising a support and front and rear layers of silver halide emulsion spread on the opposite faces of the support, and a front and rear pair of reinforcement screens respectively adjacent to said front and rear emulsion layers , wherein at least one of said silver halide emulsion layers shows a swelling index of less than 140% and a melting time between 45 and 120 minutes, and the difference in contrast between the pair of silver halide emulsion layers is at least 0.5, in which the difference in light emission, stimulated by the X-rays between said pair of reinforcing screens is at least 0.6, and in which the average cross-over as an image of said radiographic element is less at 5% at optical densities between 0.5 and 1.75 and in the range between 5% and 15% at optical densities between 1.75 and 3.25, said cross-over as an image being measured to according to the formula described in the description.
